Aaron and I are watching Alex play with his Stack & Roll Cups he got for Christmas, and we are totally mesmerized by him attempting to figure out how they go together. He has three of cups, and just isn’t sure how to make them fit. He knows that the sizes and colors matter. He tries to put the light green one with the dark green one, knowing that they are together in the sequence of the stacking. At one point he managed to get two into a ball. Some of my favorite moments are simply just watching him.
